Directions : Read the passage given below and answer the questions that follow (Q. Nos. 131 to 138) by selecting the correctmost appropriate option. Dorothy lived in the midst of the great Kansas prairies (grasslands) with Uncle Henry, who was a farmer, and Aunt Em, who was the farmer's wife. Their house was small, for the lumber to build it bad to be carried by wagon from many miles afar.

When Dorothy stood in the doorway and looked around, she could see nothing but the great gray prairie on every side.

Once the house had been painted, but the sun blistered the paint and the rains washed it away, and now the house was as dull and gray as everything else. Study the following statements: (a) Uncle Henry had a tractor trolley in which wood was caried (b) The wood for the house was carried from far away. Choose the correct option :
